Title: Sewing device
Inventor: SAKAI YASUYUKI
IPC: D05B69/00
Filed: 1989-09-28
Abstract: PURPOSE:To perform automatic sewing of a cylindrical substance with high precision by a method wherein the two ends of a substance to be sewn are grasped by a clamp means and clamp mechanisms, the feed of the clamping mechanisms end the clamp means is effected in linkage with feed movement of a sewing machine as a sewing margin is controlled by a sewing margin control mechanism. CONSTITUTION:A sewing machine is driven in a state that the upper end of a substance to be sewn is grasped by clamp mechanisms 8 and the lower end thereof by a clamp means 11. During sewing, the clamp mechanisms 8 and the clamp means 11 are fed in linkage with feed movement of a sewing machine as a sewing margin is controlled by a sewing margin control mechanism 7. Usually, the upper end of the substance to be sewn is grasped by the clamp mechanisms B and grasping is effected by the clamp means 11 in a state that the substance to be sewn is hung down. But, in order to effect proper grasping by means of the clamp means, positioning of the lower end of the substance to be sewn is effected, and it is desirable that the lower end is pressed until grasping by means of the clamp means is performed. It is desirable that the clamp mechanisms 8 on both sides to grasp the upper end of the substance to be sewn are designed so that the feed of the clamp mechanisms and that of the clamp means are regulatable individually independently.

Title: Magnetic storage element
Inventor: HIDAKA YASUHARU
IPC: H01L39/00
Filed: 1987-10-02
Abstract: PURPOSE:To obtain a high density solid-state magnetic storage element offering ease of readout by utilizing an anti-magnetism current caused in a superconduction ring so as to enhance the stability of storage information and making most of the superconduction-normal conduction transition of the superconductor ring or the Josephson junction fitted to the superconduction ring. CONSTITUTION:The superconductor wire 4 is processed to be in contact with the magnetic substance film pattern 6 and a lower superconductor wire 3 directly in an area where no 2nd superconductor wire 2 exists. Thus, the superconductor ring 5 using the Y axis direction as the normal of the face of ring while surrounding the magnetic substance is formed. Unit cells are arranged in a matrix to be used as storage elements. Then a pulse current is given to the superconductor wire 1 comprising the 1st and 3rd superconductor wires in the X axis direction and the 2nd superconductor wire 2 in the Y axis direction to invert the direction of magnetization of the magnetic film pattern 6 from the positive to the negative direction. The magnetizing state after the magnetization inversion is stabilized by the dia-magnetism current induced newly in the superconductor ring 5 in the process of the magnetization inversion. Thus, the instability of reading information attended with the improved storage density is improved and the storage element with high performance is realized.

IPC: C22C37/00
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To improve the tensile strength and fatigue strength as well as the cutting workability by specifying the size of graphite. SOLUTION: This gray cast iron has a composition consisting of, by weight, 2.8-3.8% C, 1.5-2.5% Si, 0.4-1.0% Mn, <=0.1% P, 0.02-0.30% S, 0.02-2.0% Cu, 0.01-0.10% Sn, 0.01-0.10% Ca, and the balance Fe with inevitable impurities and also has a structure of <=300μm graphite size, and further, Vickers hardness is regulated to Hv160-240.

Title: Speech signal processor
Inventor: YAMAUCHI EIJI
IPC: H04N5/937
Filed: 1993-10-07
Abstract: PURPOSE:To equalize the number of samples per frame and record digital speech signals of two systems without deterioration by converting both the signals into analog signals. CONSTITUTION:If the digital speech signals of the two systems which are supplied to 1st and 2nd input signals 1 and 2 have a difference in the number of samples per frame more than a prescribed value and when the values of sampling frequencies are different, a switch 10 is switched to a side (n). Consequently, a speech signal which is resampled matching the sampling frequency and the number of samples per frame of one system is supplied to a frame 1. A memory controller 12 outputs the speech signals of the two systems matching the number of samples per frame of one system. If, however, the number of samples per frame can not be matched because of the limitation of the capacity of the memory, an interpolator 13 performs an interpolating process so as to match sampled values.

Abstract: PURPOSE:To flatten step differences due to wirings by a method wherein the growth of an insulating film and a matter that the grown film is etched by the amount of its thickness, which is located on the wirings, are repeated. CONSTITUTION:When wirings 1 are formed on a substrate, the wirings 1 are formed putting artificial wirings 2 between them and the wirings are formed in such a way that any part of the intervals between the wirings becomes an equal interval. Then, an insulating film 3 is grown on the surface, on which the wirings 1 and 2 are formed. Then, the amount of the thickness, which is located on the wirings, of the film 3 is etched by anisotropic etching in such a way that an etching proceeds only in the vertical direction. At that time, the film 3 can be left on the sidewalls of the wirings 1 and 2. Then, an insulating film 4 is again grown. At that time, the gaps between the wirings are filled with the insulating film and the surface becomes almost flat. Then, when the amount of the thickness, which is located on the wirings, of the film 4 is etched by anisotropic etching in such a way that an etching proceeds only in the vertical direction, step differences generated due to the wirings are flattened. Then, when an insulating film 5 is grown, the wirings are covered with the insulating film and the film 5 with a flattened surface can be obtained.
